Introduction
The ACL-6126 provides 6-channel analog outputs, 16-channel digital
inputs and 16-channel digital outputs add-on card for the IBM
Personal Computer and compatible computers. It is designed for
industrial control applications requiring analog outputs ( voltage and
current )with 12-bit resolution in rugged environment.
The ACL-6126 transmits six analog outputs with various user
configurable ranges of : 0 ~ +10V, 0 ~ +5V ±10V, ±5V, and 4 to 20 mA
current loop.
Each D/A has a double-buffered output for single-step update and
occupies its own I/O location. Also, a rugged and reliable 37-pin Dsub style connector is provided for analog outputs.
In addition to the 6 analog outputs, the ACL-6126 has 16 digital inputs
and 16 digital outputs, all of the digital channels are TTL compatible.
The ACLD-9182 ( 16-bit Isolation digital input board) and ACLD-9185
( 16-bit relay output board) are designed for connection with the digital
input and output.
We apply the state-of-the-art technology and components when
designing ACL-6126. Its compact size PCB board let this card easily
fit into any kind of chassis. Also, all the components on the card are
SMT type,so it improves the reliability and quality of this card.

Installation
This chapter describes how to install the ACL-6126. At first, the
contents in the package and unpacking information that you should
be careful of are described. The jumpers and switches setting for the
ACL-6126's base address, IRQ, refernce voltage source and DA
output mode are also specified.
2.1
What You Have
In addition to this User's Manual, the package includes the following
items:
Ø
ACL-6126 6-channel Analog Output Card
Ø
ADLINK CD
If any of these items is missing or damaged, contact the dealer from
whom you purchased the product. Save the shipping materials and
carton in case you want to ship or store the product in the future.
2.2
Unpacking
Your ACL-6126 card contains sensitive electronic components that
can be easily damaged by static electricity.
The card should be put on a grounded anti-static mat. The operator
should be wearing an anti -static wristband, grounded at the same
point as the anti-static mat.
Inspect the card module carton for obvious damage. Shipping and
handling may cause damage to your module. Be sure there is no
shipping and handling damage on the module before processing.
After opening the card module carton, extract the system module and
6 • Installation
place it only on a grounded anti-static surface with components side
up.
Again inspect the module for damage. Press down on all the
socketed IC's to make sure that they are properly seated. Do this only
with the module place on a firm flat surface.
Note : DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN
DAMAGED.
You are now ready to install your ACL-6126.

Jumper and DIP Switch Description
You can configure the output of each channel and base address by
setting jumpers and DIP switches on the ACL-6126. The card's
jumpers and switches are preset at the factory. Under normal
circumstances, you should not need to change the jumper settings.
A jumper switch is closed (sometimes referred to as "shorted") with
the plastic cap inserted over two pins of the jumper. A jumper is open
with the plastic cap inserted over one or no pin(s) of the jumper.
2.5
Base Address Setting
The ACL-6126 requires 16 consecutive address locations in I/O
address space. The base address of the ACL-6126 is restricted by
the following conditions.
1. The base address must be within the range 200hex to 3F0hex.
2. The base address should not conflict with any PC reserved I/O
address. See Appendix A.
The ACL-6126's I/O port base address is selectable by an 5 position
DIP switch SW1 ( refer to Table 2.1). The address settings for I/O port
from Hex 200 to Hex 3F0 is described in Table 2.2 below. The default
base address of your ACL-6126 is set to hex 2C0 in the factory( see
Figure 2.2).

A hardware interrupt can be triggered by the external Interrupt signal
which is from pin 17 of CN3 connector. Its corresponding interrupt IRQ
levels can be selected by jumper JP7. The jumper setting is specified
as below:

D/A Output Configuration
The ACL-6126‘s output channels can be configured as different
analog output styles, and they are dependent on D/A converter's
reference voltage source and output mode( Bipolar or Unipolar). The
reference voltage can be generated internally or by external reference
voltage from the Reference Voltage Input ( REF.IN) of connector P1.
Each output channel and its corresponding jumpers are listed as
follows.
